Food: How to tell if your eggs are fresh?

Fill a container up with warm water. I use warm water. The reasonfor this is that eggs are porous. If you put an egg in cold water, it willcontract and draw any bacteria that is on the outside of the shell inthrough the pores. This is not good. So, if you use warm water, theegg will expand, and you will notice that little air bubbles form onthe shell.

Put your eggs into the warm water, and look at them. A very freshegg will sink to the bottom and lay on is side. Week old eggs willrest on the bottom but the fat end of the egg will rise up slightly.Three week old eggs will be balanced on pointy end with the fatend sticking up. Old eggs will be floating, bobbing along the surfaceof the water. These floaters should be tossed as they aren't any goodto eat.
